South Sudan's minister of cooperatives and rural development Jimmy Lemi Milla and his bodyguard were shot dead on Wednesday, the southern army's spokesman said, in what appeared to be a personal dispute.
"There was shooting at the ministries (complex), in which the minister of cooperatives and rural development was killed, as well as his bodyguard," the Sudan People's Liberation Army spokesman Philip Aguer told AFP.
"It is believed that the man responsible was the minister's driver, and he also killed himself," he added.
Aguer said the exact reason for the shooting was not known.
"They all came from the same ethnic group, and it's possible that it was a personal matter," he said.
